🏋️‍♂️ What Is a Bulking Cycle?

A bulking cycle is a caloric surplus phase supported by performance-enhancing compounds to:

• Increase lean muscle mass
• Boost strength
• Speed up recovery
• Enhance protein synthesis
• Support higher training intensity

These cycles typically run for 8–16 weeks depending on goals and compounds used.

⚠️ Bulking Cycle Tips

• Train heavy + progressive overload

• Run bloodwork mid-cycle and post-cycle
• Plan your PCT before starting

🧬 Legal Alternatives to Bulking Steroids

For those not ready to pin or cycle AAS, consider legal OTC bulking options like:

• D-Bal (mimics Dianabol)
• Testo-Max (natural testosterone booster)
• Trenorol (mimics Trenbolone)

These offer moderate gains with no suppression or harsh side effects.
